The 3000WFR series is a family of compact 25W to 30W, high

performance DC/DC converters. These converters are

specifically designed to provide the flexibility, power density,

and reliability required to fulfill local power needs in

applications ranging from telecom switch systems to

portable instrumentation. 27 models operate over 2:1 input

ranges of 9 to 18, 18 to 36 or 36 to 72 VDC; providing single,

dual or triple output combinations of 3.3, 5, 12, 15, ±5, ±12,

±15, 5±12 and 5±15 VDC. All models are packaged in

compact, low profile 2.0” X 2.0” X 0.4” metal cases.
